Hi, all. I brought home two new boys on Monday, and they've both been in monitoring bowls so I can keep an eye on them before I transfer them to tanks. Today one of them started acting strangely, and it's worrying me. I did a partial water change at about 5:00 today (it's now 9ish)-- since he's in a 1 gallon bowl, I do 100% changes every other day, but I was already in the middle of doing three other water changes in the viscinity so I decided to freshen his up a little. I fed him one pellet-- he hasn't had an amazing appetite lately, but he's only been home for two days so I figured that might just be him adjusting-- and he didn't eat it right away, so I figured I'd leave it for him and check back later to see if he'd eaten it.
The pellet is now apparently gone, but I decided to sit with his tank a little bit to check up on him and noticed some strange behavior. He's extremely sluggish compared to how energetic he was earlier today-- wouldn't move for anything short of me gently tilting the bowl. He swam around for a few seconds, but then did what I can only describe as 'burping'-- it looked like he was trying to bring something up, and I heard a 'clicking' noise. He took a few gulps from the surface, slowly swam around a bit more, 'burped' again and finally went to rest on one of the leaves of his plant, situated so he could just tilt his head up to get more air if he needed to. Every few minutes, his body would 'jerk' a little bit and he'd make the burping motion again, gulp down some air, and then lay back down.
He doesn't seem distressed-- when he DOES swim, he manages it fine, and he isn't breathing rapidly, but he absolutely does not want to move and doesn't respond to fingers/gentle water movement/any other form of stimulus short of actually forcing him to move. I'm really worried.
